'T'iillwhom it may concern:

Beit-known thati, THOMAS WATKINS, of Wilson, in the county of Allegheny, State of Pennsylvania, have invented a new. and useful Improvement in Dun'iping Devices, of which the following a full, clear, and exact description, reference being bad to the accompanying drawing, forming part of this specification, in which Figure 1 is a side elevation partly in section showing the receivingpan in its normal position; Fig. 2 is a like view showing the pan lowered and in its forward dumping position Fig. 3 is a like view showing the pan in its rear dumping position 2 Fig, is a side elevation of the an; Fig. 5 is s. sectional l'an view on the line VV ofl ig. 4; Fig. 6 1s a vertical transverse section on the line VP-Vi oi Fig. 4.

My invention relates to an improvement in dumping devices which may be employed for the purpose of dumping coal, ore or other material, and it is especially applicable for the purpose of loading barges or other vessels, although I do not desire to limit its use to this or to any other purpose.

Heretofore in tipples, ordinarily used in dumping coal into coal barges, as distinguished from traveling buckets, it has often been necessary to change the location of the barge in order to bring the load to proper position athwartship, the tipple being so constructed as to dump at but one or two points. As the craft einployedin carrying coal are of various widths, ranging from sixteen to twenty feet, and as it is necessagy to distribute the load at desired points'in the barge, the need of a tipple capable of such distribution has long been felt in the art.

The object of iny invention is to provide a dumping device of the ordinary type, having a tilting-pan capable of adjustment to dump at any desired point athwartship of the craft which is being loaded, and appliances for causing such adjustment and for-opera ing the tilting-pan. I

i will now describe my invention. so that others sl lled in the art may manufacture and use the same.

in the drawing "2 represents the vertical frame of a coal tipple, 3, 3 the horizontal arms or supporting beams, and i, the chute which delivers the coal to the tiltingpan. Journaled suitable bearings on the arms or, beams 13, are the drums 5 and 5"},

provided with gear-wheels 6 and tvl mesh with each other. On thedruin 5 are wound lines 7, provided at their lower ends with chains 8 which are connected to the rear lower corners of the tiltingpan 9. VVoun-i on the drum 5 are lines 7 which pass'over guide sheaves 1,0 and are provided at their lower ends with cl'i-ains 8 which are connected to the forward lower corners of the pan 9. This tilting-pan 9, at its forward end is provided with a swinging door 11 which is sopivoted to the pan as to beopened when the end of the penis tilted in dun'iping the coal, the door being provided with a line 12.

extending over the s leave 13 and extending to the spools 5 on the rollers 5 on which it is wound.

Secured to the bottom of the pan 9, at each side thereof, is a ii-shaped guideway 14, which may be formed of angle bars. Travel ing in the ways 14 arerollers or wheels 15 which are journaled in the end of the rods or bars 16, the other ends of which are ivot-ed to the sliding weights 17 which are tted to slide on the vertical rodsfiS secured to the frame or standard 2. These weights are provided with lines 19 wound on the smaller diameter of the drum 20 which is journaled in suitable bearings on the horizontal arm or beam 3*. Eivoted to the bottom of the pan 9, at BBJOhj/ TCIG thereof, are bails 'b,-whic h are com osed of two or more lower upwardly exten ing arms 22 and 22 which. are pivoted to two upwardly extending arms 23 and 23 the outer or upper ends of which are pivoted to each other. Pivoted to the joints between' the arms 22 and and 22*? and 23 are the cross arms 24. Secured to the balls 1) at the upper ends of their extension rods 25 are the ines 25 which are wound on the larger diameter of the drum 20. The lower portion 4 ofthe chute is supported from the arms 3 by the rods 26. In the flanges of the angle bars of the way 14 are holes'27 through which the pins 28; are adapted to pass. These pins may be provided with rubber or leather sleeves 29. These holes may be an ranged at suitableequal distances from the a ex of the way'14 and serve as fulcruins for t e rods or bars 16 during the dumping op-' eration;

The operation is as follows: Thepan 9 having been brought to its normalposition, shown in Fig. 1, the coal or other material is allowed torun down the chute 4, 4 into the pan. When the pan is full and it is desired.

to dump the coal or other rnaterial forwardly into the barge c or other receptacle, the drum 20 is caused to rotate in thedirection to pay out the lines 25 and 19, causing the pan 9 to be lowered to the desired horizontal position above the barge c. If the lengths of the chains 8 and 8 have not been previously adjusted, the drums and 5 may then be caused to rotate in the direction opposite to the door 11 and al that indioated by the arrows shown in Fig. 2,

which pays out the lines 7 a and winds in the lines 7, thus lowering the forward end of-the pan 9 and elevating the rear end which opens terial to be dum ed at the point determined by the combiner? action of the wheels 15 on the ends of the bars 16 and the bails b: for, as the forward end of the pan 9 is lowered the arms 22" and 23 are straightened to a vertical position, forming a support at'a point outsire of the middle of the pan, and, as

the sheave 10 and the drum 5 are further apart than the length of the an, the pull of the line 7 on the pan is away mm the side of the barge, but, as the wheels 15 bear against the pins 28, any movement of the pan away.

from the side of the craft is ,revented and the coal or other material is (umped at the port side of the barge. When it is desired to dump the coal amidship, the pin 28" is moved to the holes at d in Fig. 2, which allows the forward end ofthe pan 9 to be drawn back to the wheel 15, which,owing to the shape of the guide ways 14, will assume a lower position directly amidship. By placing .the fulcrum pin 28 at intermediate holes the point of deposit may be varied according to the width of the craft. Whenit is desired to deposit the coal atthe starboard side of the arge, dum in the coal from the rear end of the pan 9, t 1e drums 5 and 5 are rotated in a reverse direction, as shown by the arrowsin Fig. 3., which lowers the rear end of the an and raises the front end, the arms 22 am 23 being brought to substantially a vertical position and forming the support, and the pin 28 acts as a fulcrum with the wheel 15 and prevents the pan being pulled forward by the line 7. By shifting the pintothe hole at e the. pan may'be caused to deposit its load amidship, and using intermediate holes the point of deposit may be varied accordingly.

As the chute 4, 4 throws the coal or other ws the coal or other mathe specific devices shown in the drawings.
